3. Detecting sound devices

After wtfplay-live is booted you will see the welcome note with some
essential information and the Linux command prompt at the bottom. At this
stage, we want to see what audio devices are available. In order to do this
type following command and press ENTER:

snd_scan

After successful execution you should see on the screen a table with audio
devices and their identifiers (hw:0, hw:1, etc…)

Remember the identifier of the device that you want to use. It is going to be
needed very soon.

4. Checking what storage is available

Now you need a hard disk or USB memory stick with FLAC/WAV files to play.
If the drive is not connected to your PC, please connect it now. And you may
remove the wtfplay-live boot disk. It is no longer needed.

Check what disks are available by running display_mnt command:

display_mnt

The command will display a table with all mounted file systems. You should see
on the screen something similar to this:

5. Starting UI: wtfcui

Instead of running wtfplay from the command line you can run it via UI called
wtfcui. That is an easier and quicker way to get started than using command line.

You will need the audio device identifier from the previous step.
wtfcui should be started with parameter -d DEV, where DEV should be
substituted by your audio device identifier. Here are examples how this should
be entered:

If the audio device identifier that you want to use is hw:0 type:

wtfcui -d hw:0

If the audio device identifier that you want to use is hw:1 type:

wtfcui -d hw:1

And similarly for other audio device identifiers in your system. After you type
the command hit ENTER key to run wtfcui.

Directly after start, wtfcui displays a help screen. Please read it
carefully as it provides essential usage information. You can close the help
screen by pressing any key. Next, you will see the main user interface
similar to the one below:

The left column is the file browser, the right column is the playlist. You
can switch between then with the TAB key.

Navigate through the menu in the file browser with arrow keys, ENTER and
BACKSPACE to find WAV or FLAC files that you want to play. Once you highlight
the file you want to play, add it to the playlist by pressing A. You can add
more files if you want.

Now switch to the playlist on the right by hitting TAB, highlight the file
that you want to play (arrow keys again) and press ENTER. This should start
the playback and you should hear the music coming from your speakers or
headphones.

If your music plays, then congratulations! You have successfully completed this
tutorial.

6. Troubles

If the file does not play or something does not work please refer to the full
manual, that you can find here.
It provides complete information about wtfplay.
